We have discussed Azure Active Directory basics at length in our earlier article. Now, we will introduce you to Domain Services of Azure Active Directory.
Azure Active Directory Domain Services allow you to access cloud-based applications available in the on-premise IT Infrastructure of an enterprise for its data transactions and operations.
This Azure product by Microsoft allows you to run your applications on Azure virtual machines. You work on a virtual network on Microsoft's cloud infrastructure using the latest authentication protocols and without deploying domain controllers.
Admins can grant machine access to AAD tenants and users can access the applications through their existing official login credentials. Azure AD Domain Services provide managed domain services such as domain join for machines in Azure, application of group policy, read-only LDAPaccess, Kerberos/NTLM authentication, etc. These services are fully compatible with Windows Server Active Directory and are easy to deploy.

Azure Active Directory Domain Services integrate with your existing applications and migrated workloads to provide identity services in the cloud. A pair of Windows Server domain controllers manage the Azure Virtual Machines to provide you with a synchronized hybrid environment. The domain services perform one-way synchronization from on-premise directory to the Azure Ad tenant using Azure AD Connect. The resources created on Azure Domain Services are not synced with Azure AD Directory Services.
You can also deploy Azure Active Directory Domain Services for cloud-only organizations by positioning a Virtual Network and a dedicated subnet within it. Microsoft creates two Domain Controllers in the subnet and allows you to use Azure AD Domain Services features like domain join, LDAP read, LDAP bind, Group Policy and authentication of NTLM and Kerberos. Configuration of Azure AD Connect is not required as there is no need for identity synchronization.
The essential functions of Azure AD Domain Services include:

Thus, Azure Active Domain Services provides a” DO IT YOURSELF” approach to all kinds of application deployment. The applications can be deployed on a cloud server with a standard cloud domain so that your on-premises AD environment is completely separate. With just simple cloud credentials you can deploy multiple applications with a single virtual machine.
If your Infrastructure requires you to create connect your Azure resources to on-premises network, then also you can do it by creating duplicate domain controllers or creating Expressroute connection that will not disturb the actual network firewall.
Modern organizations are leveraging the best authentication solutions. Azure Active Directory Domain Services are managed by Microsoft so they offer you limited control of the domain and do not require patching of domain controllers.
